Question
1] is the process that uses oxygen to break the molecule of sugar down to carbon dioxide and water, with carbon dioxide being given off as a waste product.
Solution
The process you're referring to is called Cellular Respiration. Here are the steps:
-
Glycolysis: This is the first step, where glucose (sugar) is broken down into two molecules of pyruvate. This process occurs in the cytoplasm of the cell and does not require oxygen. It also produces 2 ATP (energy molecules) and 2 NADH (electron carrier molecules).
-
Pyruvate Decarboxylation: In this step, the pyruvate molecules are transported into the mitochondria, where they are converted into Acetyl CoA, releasing one molecule of carbon dioxide each.
-
Citric Acid Cycle (Krebs Cycle): The Acetyl CoA enters the citric acid cycle, where it is broken down into carbon dioxide. This process also produces 2 ATP, 6 NADH, and 2 FADH2 (another type of electron carrier).
-
Electron Transport Chain: This is the final step, where the NADH and FADH2 produced in the previous steps are used to create a large amount of ATP (around 34 molecules). Oxygen is used in this step to accept the electrons and protons, forming water.
The carbon dioxide produced in steps 2 and 3 is released as a waste product, which we exhale. The water formed in step 4 is also a waste product.
